Commonly used between two BFFs, Mr Fox originated from the film, 'Vacancy.' In a scene where a man (Mr Fox) is trying to call the police because someone is trying to kill him in a hotel. Mr Fox is unknowingly speaking to the killer on the phone, until the man proceeds to call him by his name 'Mr Fox,' thus giving away the fact that he is infact the killer. Mr Fox then proceeds to run out of the phone booth towards his hotel room whilst the killer chases him in his car.

This name is not to be confused with 'Fantastic Mr Fox' which is a children's novel written by Roald Dahl, first published in the US by Alfred A. Knopf in 1970 with illustrations by Donald Chaffin.
